c# - 仅当用户电子邮件地址包含破折号时，AddToRole() 才返回 "User name can only contain letters or digits"

Question

我使用的是 Asp.Net Identity 2.0，配置后用户的电子邮件地址也是用户名，因此在 IdentityConfig 中，我在 ApplicationUserManager 构造函数中设置了 AllowOnlyAlphanumericUserNames = false:

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser> store)
        : base(store)
    {
    }

    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
    {
        var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
        // Configure validation logic for usernames
        manager.UserValidator = new UserValidator<ApplicationUser>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };

        // ... other options removed
    }
}

我在一个页面中使用此代码，供员工在选中所有可用角色的 GridView 中的复选框时搜索用户并向用户帐户添加角色:

//protected UserManager<ApplicationUser> um = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));

//changed this to call the ApplicationUserManager instead of UserManager to make sure AllowOnlyAlphanumericUserName = false is called, but still no luck
protected ApplicationUserManager um = new ApplicationUserManager(new UserStore<ApplicationUser>(new ApplicationDbContext()));

protected void cbRole_CheckChanged(object sender, EventArgs e)
{
    string UserName = lblUsername.Text;
    if (!String.IsNullOrEmpty(UserName))
    {
        CheckBox cb = (CheckBox)sender;
        GridViewRow row = (GridViewRow)cb.NamingContainer;
        string Role = row.Cells[1].Text;

        if (cb.Checked)
        {
            var user = um.FindByName(UserName);
            var UserResult = um.AddToRole(user.Id, Role);

            if (UserResult.Succeeded)
            {
               lblRoles.Text = "The <b>" + Role + "</b> role has been added for " + UserName;
            }
            else
            {
                foreach (var error in UserResult.Errors)
                        lblRoles.Text += error; //<-- RETURNS ERROR: "User name <email address> is invalid, can only contain letters or digits." If <email address> contains a dash (-).
            }
        }
        else
        {
            um.RemoveFromRole(hfAspUserID.Value, Role);
            lblRoles.Text = "The <b>" + Role + "</b> role has been removed for " + UserName;
        }
    }
}

它通常运行良好。但是，只要用户的用户名中有破折号，例如“users.name@domain-name.com”，AddToRole() 函数就会返回错误 User name users.name@domain-name.com is invalid , 只能包含字母或数字。

所有帐户都是本地帐户，未配置为使用外部登录，例如 facebook 或 Google。

如果您能提供任何帮助，我们将不胜感激，因为我对这个问题进行了广泛的 Google 搜索，除了关于如何将电子邮件地址实现为用户名的教程外，什么也没有找到，我已经完成了。

请学习并遵循这段代码，它有效:

        var db = new DBModel();
        DBModel context = new DBModel();
        var userStore = new UserStore<User>(context);
        var userManager = new UserManager<User>(userStore);
        userManager.UserValidator = new UserValidator<User>(userManager)
        {
            AllowOnlyAlphanumericUserNames = false
        };
